KP2928-2 - Lincoln Electric KP2928-2 SAW Contact Nozzle 1/8 Inch

Precision Contact for Submerged Arc Welding

Maximize the efficiency of your welding operations with the Lincoln Electric KP2928-2 Contact Nozzle. This premium consumable is engineered to handle the substantial electrical loads associated with welding 1/8 inch (3.2 mm) wire. Often the unsung hero of the welding setup, the contact nozzle plays a pivotal role in current transfer. The KP2928-2 is manufactured with precision-drilled bores that ensure optimal contact between the nozzle wall and the passing wire, facilitating a smooth and stable arc that is crucial for high-quality heavy fabrication.

Durability is a key feature of the KP2928-2. In Submerged Arc Welding (SAW) and large-diameter flux-cored applications, the friction of the wire and the intense heat of the arc can rapidly degrade inferior consumables. Lincoln Electric utilizes high-quality copper alloys that provide superior thermal conductivity and hardness. This material choice helps dissipate heat effectively, preventing the nozzle from overheating and softening. Consequently, the nozzle retains its shape and dimension for longer periods, reducing the frequency of changeovers and keeping your production line moving.

Using the correct size nozzle is non-negotiable for achieving sound welds. A nozzle that is too tight will cause drag and feeding issues, while one that is too loose will result in intermittent electrical contact and arc sputtering. The KP2928-2 is specifically sized for 1/8" (3.2mm) wire, offering the perfect balance of clearance and contact. This precision helps eliminate micro-arcing inside the tip, which is a common cause of premature failure and wire jamming. For welders working on critical infrastructure, pressure vessels, or shipbuilding, the consistency provided by this nozzle is invaluable.

Genuine Lincoln Electric parts are tested to ensure compatibility and performance with their welding systems. By choosing the KP2928-2, you are ensuring that your torch assembly functions as intended by the manufacturer. This nozzle is an integral part of the current path, and its performance directly impacts the deposition rate and penetration profile of the weld. Keep your heavy-duty welding equipment running smoothly with this essential replacement part, designed to deliver professional results shift after shift.
